A wonderful good evening. I have seen a little bigger, deeper scratch marks on my KS700 at Bock No. 8. At the storage place of the camshaft you can also see light bars. What does it look like with the tolerance range for this? How worn out can there be bearing bells, camshafts at all, in order to ensure a normal function? Or is the head now scrap????? I hang up a picture, vllt. clarifies this a little my explanation… Hope on An word and leave with a greeting, Sasha
